T0 at whom it may concern.- 4 Be it known that I, JEREMIAH A. PAIGE, of

Manchester, county of Hillsborough, and State 1 of New Hampshire, have invented an Im provement in Apparatus'for Sweeping and Clearing Streets, of which the following de-' scription, in connection with the accompanyingdrawings,is a specificationdike letters and numerals 0n the drawings representing like parts. i

This invention hasforits object to improve the construction of machines for sweeping and clearing streets of that type wherein the material collected by the clearing device is delivered to a carrieror conveyor which is operated to deliver it to a suitable receptacle; and the invention consists ina wheel-supporting frame, an oblique clearing device car'- ried by it, which may be a brush or a board or any equivalent device, a moving carrier or conveyer, a receiving-chamber located at the rear end of said clearing device having an open bottom beneath which said carrier moves, and means for operating said carrier or conveyer to raise the material and deliver it to a receptacle adapted to receive it; also, in means for concealing the dirt-carr'ying receivers of the moving carrier or conveyer as they pass from said receiving-chamber to the point of delivery; also, in adjustable means for holdingthe clearing device relative to the carrier or conveyerto compensate for wear of the clearing device; also, in certain details of construction, as will be hereinafter pointed out. i

Figure 1 shows in side elevation a machine for sweeping and clearing streets embodying this invention. Fig. 2 is a plan view of the machine shown in Fig. 1. Fig. 3 is a rear end view of the machine shown in Fig.1; Figs. 4,

5, and 6, details of the clearing device to be' referred to; and Fig. 7, a modification showing two clearing devices, and consequently two carriers or' conveyers which receive the material collected by them and which deliver it to a receptacle adapted to receive it.

in any suitable manner.

13 represents a: clearing device, which is shown in Figs. 1 to 3 asa cylindrical brush having journals 1) at its ends supported in suitable bearings, as will be described. The brush B is disposed obliquely to the wheelsupporting frame, as best shown in Fig. 2. To one of the journals .1) of said brush a sprocket-wheel l) is secured, over or around which passes a chain 19 which also passes over or around a sprocket-wheel 5 mounted upon one end of a rotating shaftb and adapted to be connected with said shaft byany suitable cluteh mechanism. Theshaft b extends obliquely across the frame in paralleL ism with the brush Band is supported in suitable bearings, and said shaft b has secured ,to it at its rearmost end a bevel-gear D which is engaged and driven by a bevel-gear 6 secured to the axle 6 bearing the groundwheels A A The ground-wheel A is connected with said axle b by means of a ratchetwheel 20 and pawl 21, as is common, to provide for positively rotating the axle as the machine advances and to permit the machine being moved rearwardly without turning said axle. As the machine advances along the road the ground-wheel A will revolve the axle b and through the mechanism thus described will rotate the brush B.

The end journals 1) of the brush B instead of being mounted in and supported by ordinary bearing-bones each have loosely mounted upon them a pinion 0, (see Figs. 4 and 5,) and said pinions 0 rest upon and engage sets of rack-teeth a, formed at or along the lower side or edge of an oblique or diagonally-disposed slot ciprovided at or near the lower end of a bracket 30, depending from the frame, and said journals 1) are free to revolve in said pinions c, which thereby serve as bear- The brush B will be bodily raised and lowered, and as it is thus moved its journals b will follow in the ob lique slots 0 the pinions a rolling 'along on the rack-teeth 0, upon whichth ey rest.

By providing oblique slots 0 for the journals of the rotating brush it will be seen that veyer, and it will be seen that by providing the oblique slots 0 the brush may be moved downward and also forward at the same time to compensate for the bristles wearing away and the rear end of the brush thus always caused to occupy the same relative position to the carrier or conveyer regardless of the length of the bristles; The brush may also be raised whenever desired, so as to haul the machine about without sweeping. It will also be seen that by mounting the journals of said brush in pinions which rest upon and freely move along the rack-teeth c the movement of said brush along the oblique slots c is much facilitated and its correct position maintained;

To each journal b of the brush 13 a pulley d is loosely mounted, and to each pulley (Z one end of achain or cord d is attached, and the opposite ends of said chains or cords are attached to similar pulleys (1 both of which are rigidly secured to a rock-shaft (Z having its hearings in the brackets 30, and as said shaft 61 is rocked the pulleys d borne by it will' be turned more or less, and consequently the pulleys d on the journals I) of the brush will be correspondingly turned and the brush raised and lowered according to the direction of movement of the rock-shaft (1 In front of the brush B a fender e is located, which is herein shown as supported by chains or cords e e which are attached to the upper edge of the fender and'which pass up and over suitable pulleys, as 6 supported by the frame, and thence to two pulleys e 6 to which said chains are attached, and said pulleys e e are both rigidly secured to the said rockshaft (1 so that whenever said shaft d is rocked the fender Q will be raised and lowered with the brush. The fender c has eyes 6, whi'chreceive a guide-rod 6 depending from the frame. The fender e is disposed obliquely to thewheel-supporting 1 ram e, being arranged in parallelism with the brush B, and it has at its-rear end a shoe a or in lieu of said shoe a rearward extension may be provided on the fender, and. said shoe 6 extends rearward and terminates adjacent the carrier or conveyer.

Any suitable means may be employed for rocking the shaft (i to raise and lower the brush and fender; but for the purpose of illustration a pulley f is journaled to an upright or support f, and a chain or cord is attached to said pulley j, which passes'over or a pawl f to prevent backward movement of the pulley f. The pawl f is pivoted at 32 to the upright or support f, and it has connected to ita link f which is connected to a foottreadle f, so that said pawl may be at any time thrown out of engagement with the ratchet-wheelf in order that the pulley f may be turned in the opposite Way.

The carrier or conveyer which isprovided at the rear end of the brush'B or other form of clearing device serves to take the material collected by said brush or other clearingdevice and deliver it to a receptacle g, adapted to receive it. The receptacle g may be of any suitable description, but is herein shown as a box-like structure mounted upon rollers g on the frame, so as to be easily removed;

Upon the axle b is mounted a circular plate a, (see Figs, 1, 3, and 6,) which is'ri'gidly secured to the frame, and thereby held stationary, and said circular plate at iscut away at'its lower end to provide an opening 40,

and a shell or casin g is secured to the plate n at the opening 40, which is formed with an outer wall 45, a top wall 41, a front end wall 46, and a rear end wall 47 to thereby pro' vide a receiving-chamber 41, having an opening at one side and also at the bottom. The

side opening of the receiving-chamber n is made large enough to admit the rear end'of a brush B in such manner that said brush can sweep the material collected by it into the chamber. The circular platen is cut away at its upper edge to provide another opening 43, which is located above the receptacle g, and an oblique board n issecured to said plate n at said opening 43,- so that any material which is deposited thereon will be caused to fall by gravity through the opening 43 and into the receptacle g. The oblique board 01 with the opening 43, thus serves as a delivery-chute for the material. The ci r= cular' plate n has also secured to it ata short distance within its outeredge a circularrim M, which extends from the shell or'case 41, oneach side thereof, up tothe oblique board 71 although said rim n may be omitted, if desired. tached to and supported by it will be directly opposite one ofthe ground-wheels-as A, for instance-the axle 12 passing through it, and said circular plate will be made of a diameter approximately equal to the diameter of said ground-wheel or a little less. Acircularrim 0 is attached to the rotating ground-wheel A, being made of the same diameter'as' the rim of said wheel, and for simplicity of con struction it is herein shown as an extension The stationary plate a and parts-at- V that its vanes will side, and a carrier or of the rim of said wheel, and said circular rim 0 has secured to its inner side a number of curved vanes 0, which project inward. The circular rim 0 and vanes carried by it revolve with the ground-wheel A, and said rim is located close to the circular plate 02', so move along beneath the open bottom of the receiving-chambern and over the top of the oblique board a and as said rim 0 revolves the vanes will take the material from the receiving-chamber n and will carryit up and deposit it upon the oblique board M. The circular plate 72 will or maybe fitted within the circular rim 0 to thereby serve as an end wall for said carrier, and the circular rim n will serve as an innerwall, being so disposed relative to the moving vanes that the latter may move along freely without touching it, and the folly of the groundwheel A substantially closes the outside of the recess thus provided and in which said vanes move. Thus it will be seen that the circular rim 0 and vanes carried by it serve as and constitute a carrier or conveyer which receives the material and conveys it to the receptacle 9 and that said carrier or con veyer will continually pass beneath the open bottom of the receiving-chamber n, and thereby serve asa moving bottom therefor upon which the material is deposited by the clearing device, being directed thereon more or less by the walls of the shell or case 41.

In some cases the shell or casetl may be omitted and the material deposited directly upon the rotating carrier or conveyer, but as the walls of said shell or case effectively assist in directing the material onto the carrier or conveyer I-prefer to employ it.

In Figs. 1 to 3 a single carrier or conveyer is shown; but in Fig. 7 two carriers or conveyers, constructed substantially alike and like the carrier or conveyer shown in Figs. 1 to 3, are provided, one for each ground-wheel, and in such case two oblique clearing devices will be provided extendingin opposite ways.
